Be it known that l, ALVINR. GONZALEZ, a citizen of the United States,lresiding at Los Angeles, in the countyof LosV Angeles and State ofCalifornia, havefinvented new `and useful Improvements in RailroadConstruction, of which the following isa specication.

This invention relatesto railroad construction, and the method offorming the same, and is particularly directed yto that typeof railwayconstruction in which the ties are formed of reinforced concrete ormaterialof a similar nature, having embedded therein suitable meanswhereby the' rails may be firmly secured thereto 4in properly gaged andparallel relation.

The main object of my invention is to provide a method of constructing afirm, substantial, indestructible and cushioned railway, whereby theties may be conveniently formed on the spot and the rails laidprogressively, thus eliminating the time and expense incurred by lirstmanufacturing the ties at a central point, transporting' them to thework and leveling and truing them to receive the rails.

Other objects will appear in the following description, will be pointedoutin the claims and will be embodied in the accompanying drawings, inwhich:

igure 1 is a plan view of a portion of the road, showing the method ofconstructing the same.

Fig. 2 is a fragmental longitudinal section of the same, taken on theline` 2--2 of Fig. 1.

Fig. 3 is a transverse section of the same, taken on the line 3-3 ofFig. 1.

Fig. 4 is an enlarged longitudinal section of a fragment of the road aswhen finished and ready for commercial use, taken on the line 4*-4 ofFig. 5.

Fig. 5 is ari-enlarged transverse section of a fragment of the road.

Fig. 6 is a vertical sectional view of the tie plate.

In constructing the road I `first provide a road bed 10 of suitabledepth and width, which is composed of broken rock and hot oil, properlyleveled and rolled down in order to give resiliency and to avoiddeadness to the rails. Mounted on the road bed 10, and spaced suitablyapart are the temporary ties 11, which are of usual shape and preferablyformed of wood. Mounted on the tops of it would appear ties 11 are theblocks 12, and mounted on blocks 1'2 are the rails 13, which are securedto ties 11 by means ofthe usual spikes 14 which pass through suitableperforations in blocks 12 and are driven into ties 11.

The tiesand rails as above described are only temporary laid and serveas a means for carrying forward progressively the materials for formingthe road bed 10, and the permanent ties 16. 'lhe blocks 12 serve. toelevate the rails 13 a suitable distance above their ultimate level, inorder that the cement ties'may be conveniently formed.

In order to build up the permanent ties 16, a board 17`is placedparallelwith a tie 11, and spaced therefrom a distance sulicient to forma tie ofthe width desired. Suitable longitudinal mold boards 18 and 19 areplacedv adjacent the endsof ties 11, asshown in Figs. 1 and 3, in orderthat the length of the ties 16 may be properly gaged. The boards 17, 18and 19 and the sideV of tie 11 combine to form a mold for the buildingup of the permanent ties 16. Cement is then dumped into the mold thusformed, and built up a suitable distance, and then a suitable steelreinforcement member 21 is inserted into the cement, as well as suitablepermanent rail fastening sockets 22. The cement is then tamped aroundthe members 21 and 22 and formed to a level with ties 11, as clearlyshown in Figs. 2 and 3 of the drawings.

The reinforcing member 21 comprises a pair of oppositely disposed angleirons 23, which are disposed in longitudinal relation with the tie 16,and are secured together by means of a plurality of transverse straps24, which are riveted thereto as shown.

Each of the sockets 22 comprises a rectangular tube which is closed atits bottom and open at its top, and is provided adjacent its lower endwith an indent 26 adapted to receive the bent end of a fastening spike27. The sockets 22 are properly gaged when they are embedded into thecement ties 16, in order that the rails Vwhen secured thereby will betrue and in proper spaced relation with each other.

After the ties 16 have been built up in the manner above described, thetemporary spikes 14 are drawn and one of the rails moved aside, the ties11 and blocks 12 are thenremoved and the rails are then allowed to restupon the permanent ties 16, as shown in Figs. 4: and 50i the drawings.vIn order lthat an additional cushioning effect of the rails 13 may behad, I place under said rails at each tie, a piece of tar paper or othersuitable material 29, and I also arrange a suitable tie plate 3()between said tar paper andV the rail, as clearly shown in Figs. 4 and 5.The tar paper 29Yand tie-plate 30 are both provided with suitableperforations through which pass thepermanent. fastening spikes 27. Thefastening spikes 27 are held `securely into engagementwith the iiangeoithe rails bymeans of the woodenplugs 32, which are driven into thesocketsV 22 adjacent ysaid spikes. .By means of the plugs 32, the bentends of fastening spikesl 27 are caused to project into the indents 26,thussecuring said fastening; devices securely into said said sockets. f

What I claim is: 1

1. The methodoi' progressively constructing a railway, which consists offirst forming a road bed composed of broken stone and hot oil, thenlaying Y. temporary ties and rails thereon to form a track over whichthe materialsfor forming advanced sections of the road maybe hauled,then forming reinforced permanent concretel ties on said road bedbetween said temporary ties provided with suitable` rail fasteningdevices, lthen removing said temporary ties and allowing said rails torest upon said permanent ties, and

then securing said rails to said permanent ties by means of saidfastening devices. 2. The method of progressively constructing arailway,which consists of first forming a road bed of suitably packed brokenstone and hot oil, then laying temporary ties on said bed, then placingsuitable rail elevating blocks on said ties., then laying, rails on saidblocks and securing them to--said ties to form a track over which thematerials for forming advanced sections ci permanent road may be hauled,then forming lreenorced permanent concrete ties on said road bed betweensaid temporary ties provided with-suitable rail fastening devicesthenrei moving said temporary Vties vand elevating blocks, and Vallowingsaid Vrails to restupon said permanent ties', Vand then securingsaidrails to saidperrnanent ties by means of said fastening` devices. y A Inwitness that I claim the foregoing I have hereunto subscribed my namethis 27th day of January, 1920. j
